Traccar server are getting the same position every time

I have exactly the same problem, with devices that mark the same location on the map every time.
But they are moving and this happens when in the same way in Sinotrack and other brands of equipment, so far I cannot find the solution.

But if I migrate the device to a demo server of traccar if it works correctly. Ruling out that it is a team problem.

Now with gt06 protocol. When restart docker container, it work.
Has anyone tested version 6.3?

Why downgrade Netty?
